A repair tool for Neo4j Lucene indexes in case the _id_ field goes missing in some documents. !!!THIS TOOL IS NOT SAFE TO USE ON A RUNNING DATABASE!!! You can use this in two modes. One is a standalone tool from the command line, as in java -jar lucene-store-utils.jar <path-to-database> [repair] with [repair] being an optional argument which, if present, will remove any documents it finds without the _id_ field, in all indexes created by the database. You can also use it as an embedded repair tool - see the TestCorrectness tests for sample use.
